This is a Golang code examples repo I used for learning.

TCP Client Server

• Features:

  • starts a TCP server on port 8080 by default
  • prints data the client has sent it
  • responds back to client with timestamped text message confirming data reception
  • the client currently sends a single hardcoded msg and quits after getting server ACK message back. When the -pipe flag added it alternatively can read data from Linux pipe insteaf of using the hardcoed text message e.g.:

    11:52 $ echo "Testing!" | tcp-client -pipe
    2024/01/03 11:52:22 Waiting for reply..
    Server response: 2024-01-03T11:52:22.535248794+01:00      ==> SERVER ACKed!
    

• Installation:

  • go install github.com/tomsucho/go-examples/tcp-client-server/tcp-client@latest
  • go install github.com/tomsucho/go-examples/tcp-client-server/tcp-server@latest

• Usage:

  • the above will build executable and store it under your $PATH so you then you can start each with just typing tcp-server or tcp-client.
